Abstract

A power transmission chain (10) has opposed first link members (12) arranged alternately with opposed second link members (11) along the length of the chain. The first and second link members are connected to one another in an articulated manner such that there is rolling contact between the two at respective bearing surfaces. The second link members (11) are disposed freely between adjacent pins (13). Each first link member (12) is connected in a friction fit to each end of the pin (13). The bearing surfaces run transverse to the longitudinal axis of the chain. The design reduces the polygonal effect by providing for two articulating joints between adjacent pins and significantly reduces wear by providing rolling contact at the bearing surfaces. <IMAGE>
